I see, thanks a lot Bob!

Derive a formula for the molar mass of the solute in terms of the freezing point depression, deltaT, the freezing-point constant, Kf, and the masses of solvent, msolvent, and solute, msolute, used in an experiment like this one. SHow your work and include all unites in your fi...

I get it now, thanks again Bob
Chemistry
Thanks Bob! As for deltaS, it just says Entropy increases in all spontaneous reactions, there's nothing more specified, so I assumed that it was deltaS and not deltaSuniverse
Chemistry
(b) deltaG < 0 , are product-favored and occur with rapid transformation of reactants to products. HOw is this incorrect? deltaG < 0 is product-favored and is rxn forward. Thank you
Chemistry
So when there's a spontaneous reaction, deltaS is > 0 , I confused that with increase. I still don't see how it's incorrect
Chemistry
Explain why each of the following is incorrect: (a) Entropy increases in all spontaneous reactions. Wouldn't (a) be actually correct? Because when there's a spontaneous reaction, you have less stable molecules and more disorder. It will be lower in some reactions than ...

In one room the radiator has a dark color (emissitivity = 0.818). It has a temperature of 64.8 oC. The new owner of the house paints the radiator a lighter color (emissitivity = 0.417). Assuming that it emits the same radiant power as it did before being painted, what is the t...
